By installing the slot tag along the axial direction of the rotor shaft, the rotor The copper wires at both ends will be blocked on the axial side of the rotor slot, and the coils at both ends of the rotor need to be pressed inward to expose the rotor slot, so as to facilitate the installation of the slot tag. In the prior art, the method of artificially pressing the coil is used to reshape the coil, but the efficiency is low and the labor intensity of the workers is high.

technical problem

The purpose of the present invention is to provide a rotor coil shaping device that can improve production efficiency and reduce the labor intensity of workers.

Technical solutions

In order to achieve the above objective, the present invention adopts the following technical solution: a rotor coil shaping device, comprising a positioning block and a pressing block located above the positioning block, the middle of the positioning block is provided with positioning protrusions extending upward and arranged in the front and rear directions, The width of the positioning protrusion is the same as the width of the opening of the rotor slot of the rotor, at least one end of the front and rear ends of the positioning block has an upward limiting protrusion, and an upper shaping piece is fixed on the lower side of the pressing block. The upper shaping sheet has an arc-shaped slot that opens downward.

When the device of the present invention is used, the rotor is placed on the positioning block so that the positioning protrusion is located in the rotor slot on the rotor core, and then the rotor is moved in the axial direction so that the axial end surface of the rotor core is aligned with the limiting protrusion. Then, press the pressing block down to make the arc-shaped groove wall of the upper shaping blade contact the coil and press it tightly, and then rotate the rotor to press the circumferential surface of the rotor ring tightly. Wherein, the radial limit of the rotor is realized by positioning protrusions. Wherein, the limit protrusion is used to align the coil with the upper shaping blade to avoid contact between the upper shaping blade and the rotor core when the pressure block moves downward.

Preferably, the positioning block is fixed on a positioning seat, the positioning seat is sleeved on a plurality of vertically arranged guide rods, the lower end of the guide rod is fixed to the bottom plate, and a spring is provided between the positioning seat and the bottom plate, The spring is sleeved on the guide rod, and the bottom plate is provided with an upwardly extending lower shaping piece, the lower shaping piece has an upwardly opening arc-shaped slot, and the lower shaping piece is located directly below an upper shaping piece. The above arrangement increases the area of the compressed and shaped coil each time the pressing block is pressed down, so as to improve efficiency. Wherein, the positioning block and the positioning seat can be integrated, or can be two independent components.

Preferably, both the front and rear ends of the pressing block are provided with upper shaping pieces, the front and rear sides of the positioning seat are equipped with lower shaping pieces, and each lower shaping piece is located directly below an upper shaping piece. The above arrangement improves the stability of the device of the present invention during use, and prevents the rotor from overturning when the coil is compressed and shaped.

Preferably, the positioning block is detachably fixed on the positioning seat. When the rotor is a slanted slot rotor, different positioning seats with positioning protrusions corresponding to the inclination angle are replaced according to the inclination angle of the rotor slot.

Preferably, the positioning seat is formed with an upwardly opening V-shaped groove, the V-shaped groove includes two supporting groove surfaces arranged obliquely to form a V-shaped structure, and the positioning block is fixed in the middle of the V-shaped groove so that the positioning block is located Between two supporting groove surfaces. The supporting groove surface is used to support the rotor core of the rotor to limit the radial displacement of the rotor and improve the stability of the device of the present invention during use.

Preferably, the pressure block is fixed to the output end of the press, one end of the pressure block and the guide block is fixed, and the other end of the guide block is located in the guide groove of the fixed plate, and the guide groove is arranged vertically. The guide block and the guide groove are used to guide the pressure block to prevent the pressure block from driving the rotation of the upper shaping piece.

Beneficial effect

The invention has the advantages of improving production efficiency and reducing labor intensity of workers.
